Random Polarization Position Angle Behaviors across Bursts of Repeating Fast Radio Bursts
Xiaohui Liu, Jiarui Niu, Tiancong Wang +27
Fast radio bursts (FRBs), highly polarized, mostly have a nearly constant polarization position angle (PA) during each burst. Their PAs are observed to vary from burst to burst, wi…

H I absorption line and anomalous dispersion in the radio pulses of PSR B1937+21
Jinchen Jiang, Shunshun Cao, Kejia Lee +10
We use the Five-hundred-meter Aperture Spherical radio Telescope to observe the bright millisecond pulsar PSR B1937+21 (J1939+2134) and record the data in the band from 1.0 to 1.5…
